Abstract

A method for forming a three-dimensional article comprising applying a first powder layer on a work table; directing a first energy causing said first powder layer to fuse in first selected locations to form a first cross section where said first energy beam is fusing a first region with parallel scan lines in a first direction and a second region with parallel scan lines in a second direction; fusing at least one of the scan lines in said first region in said first direction immediately before fusing at least one of said scan lines in said second region in said second direction; applying a second powder layer and directing the energy beam causing said second powder layer to fuse in second selected locations where the energy beam is fusing said first region with parallel scan lines in a third direction and said second region in a fourth direction.
